Trait OpenNodeRef

pub trait OpenNodeRef<T> {
    // Required methods
    fn is_boundary(&self) -> bool;
    fn boundary(&self) -> impl Iterator<Item = Self>;
    fn get_value(&self) -> Option<&T>;
    fn parent_value(&self) -> Option<&T>;
}

Extension trait for nodes in an open tree.

Required Methods

fn is_boundary(&self) -> bool

Is this node a boundary node?

fn boundary(&self) -> impl Iterator<Item = Self>

Iterates over boundary of tree accessible from this node.

fn get_value(&self) -> Option<&T>

Gets a reference to the value of this node, if it has one.

fn parent_value(&self) -> Option<&T>

Gets a reference to the value of this node’s parent, if it has a parent.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
